TI-36x Calculator Functions

At first glance, the Texas Instruments TI-36x Pro appears to be a standard scientific calculator. However, you will see that the TI-36x calculator functions are different from what you expect in a calculator under $20.

The calculator is simple to use and features a well-known button arrangement. The screen includes a 4 -line display, which allows for enough space for performing computations and just enough space inside menus and programs. 

The calculator has no ports since it is powered by a solar panel immediately above the display and a battery. However, the TI-36x Pro calculator includes several capabilities that you would ordinarily find solely on a graphing calculator. These features are great if you want to avoid paying the exorbitant price that comes with them.

Therefore, this calculator is ideally suited for computer science and engineering-relevant exams where a graphing calculator is not permitted, especially for the FE and PE exams, where it is one of the allowed calculators.

The scientific calculator TI-36x Pro is certified for use on SAT®, ACT®, and AP® tests.

Let’s now look at its features and other specifications in detail. You will also understand why it is one of the most preferred calculators by students.

Key Features of TI-36x Calculator

We shall now explore the key features of the NCEES® approved Texas Instruments 36x calculator :

  • Four-line text output.
  • Choose between degrees/radians, floating/fixed, and number format modes.
  • There are three solutions to choose from: numeric equation, polynomial, and system of linear equations.
  • Show a specified function in a tabular format.
  • Statistics with one and two variables
  • The MultiViewTM display displays numerous calculations on the screen at the same time.
  • For real functions, it computes the numeric derivative and integral.
  • It uses a vector and matrix entry window to perform vector and matrix operations.

Must-Know Functions for Your TI-36X Pro 

The TI-36X Pro calculator is a powerful tool for FE exam takers, offering various mathematical functions. However, to truly optimize your exam performance, it’s crucial to prioritize functions most relevant to the FE exam itself.

Why Focus on Exam-Specific Functions? The FE exam covers various engineering disciplines, but the core mathematical functions remain consistent. By focusing on these core functions and mastering their application on the TI-36X Pro, you can approach the exam with confidence and efficiency.

What Functions Take Center Stage? Some of the most commonly encountered functions on the FE exam include:

  • Trigonometry: Sine (sin), cosine (cos), tangent (tan), inverse trigonometric functions (sin⁻¹, cos⁻¹, tan⁻¹). These functions are crucial for solving problems involving angles, forces, and geometric relationships. (Example: Calculating the angle of a ramp using the sin function).
  • Logarithms: Logarithms (log) and exponential functions (eˣ) are essential for solving exponential growth or decay equations. (Example: Analyzing the decay rate of a radioactive material using logarithms).
  • Complex Numbers: The ability to perform basic operations with complex numbers (numbers with a natural and imaginary component) may be required for some FE exam problems, particularly in electrical and computer engineering.
  • Integration/Differentiation (Optional): While not as prevalent as the functions above, some FE exams involve essential integration or differentiation problems. Understanding how to utilize these functions on the TI-36X Pro can be advantageous.

Focusing on these key areas optimizes your study time and empowers you to approach the exam confidently.
